These figures cover 914 flights between September 2025 and August 2026. The median arrival is 11 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Departure window
When Republic runs best on this route
Departure time is the single lever a traveller controls, and it moves the odds more than most people expect. Each bar below is the on-time rate for flights scheduled to leave inside that window, across 914 flights.
- 5am–8am—
- 8am–11am169 flights89.9%
- 11am–2pm133 flights90.2%
- 2pm–5pm157 flights81.5%
- 5pm–8pm25 flights—
- 8pm–5am430 flights84.8%
Scale runs 75% to 95%. Rows with fewer than 30 flights show a dash.
The best window here is not the first bank but the 11am–2pm slot at 90.2% on time, ahead of 2pm–5pm at 81.5%. Where the curve peaks mid-day rather than at dawn, the constraint is usually congestion at one end rather than the aircraft's own rotation. The 8pm–5am window is the busiest, with 430 flights scheduled in it.
Across the year
Republic on DTW to CMH through the year

The worst days
Worst days for Republic on DTW to CMH
The latest arrival of the period was on 13 November 2025, 12 hours 6 minutes behind schedule; most of its delay minutes were filed as carrier-caused (crew, maintenance, fuelling, baggage). On three of the five worst days the largest share was filed as a late-arriving aircraft.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 13 November 2025 | 12 hours 6 minutes | Carrier |
| 5 April 2026 | 8 hours 26 minutes | Late-arriving aircraft |
| 14 January 2026 | 6 hours 18 minutes | Late-arriving aircraft |

Delay causes
Why Republic runs late on this route
Carrier accounts for 51% of the 10,000 delay minutes carriers reported here, and the remaining four split what is left.
- 51%Carrier
- 36%Late-arriving aircraft
- 11%National Airspace System
- 2%Extreme weather
- 0%Security
36% of delay minutes trace back to a late-arriving aircraft, meaning the plane was already behind before it got here. Across 10,000 reported delay minutes here, that single category outweighs weather by 16 to one. The split is drawn from 10,030 reported delay minutes.
The largest share of delay minutes, 51%, falls under carrier control: crew scheduling, maintenance, fuelling, baggage. It accounts for 5,081 of the 10,000 delay minutes reported here.
Cancellations are rare at 0.44%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and stage length
What a delay here costs
5.7% of arrivals land an hour or more late, close to the national 8.3%, so a 60 to 75 minute layover is reasonable here while anything under 45 minutes is a bet. Most delays on this route last a little over an hour, which a normal layover absorbs.
At 155 miles this is a short hop, and stage length matters more than it looks. A flight this short spends under two hours in the air, which leaves almost nothing to claw back a late pushback with. Delay here is decided on the ground, in the turn, which is why the 11am–2pm window matters as much as it does.
The return leg is a different operation and performs like one: it runs 89.7% on time across 916 flights, 4 points above this direction. Departure banks, aircraft rotations and the congestion at each end all differ, so scoring the two directions together would average away a real 4 points of difference.
One caution: this is a thin sample. 914 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking Republic on DTW to CMH
Put together: treat all of this as provisional. 914 flights over twelve months is enough to clear this site's floor and not enough to be confident to better than a couple of points. The 86.0% headline is the most reliable number on the page; the hour and month splits below it are built on a few dozen flights each. 910 completed flights over 12 months sit behind that.
